“…The respiration is very important parameter for studying the anthropogenic soil loading together with determination of N 2 fixed by bacteria, amount of microbial biomass, dehydrogenaze activity and humification [7]. Microbial respiration is defined as oxygen take-off or releasing of CO 2 by bacteria, fungi, fimbrias and protosoas and it include the gas interchange in aerobic and anaerobic metabolism.…”

In this paper is looked for answers on following questions: 1. Which from crop residues and bio-stimulators more affected basal, potential and relative respiration? 2. Which from crop residues and bio-stimulators more affected the changes of potential and relative respiration dynamics during incubation? Therefore a laboratory experiments were established. In pots were added soil samples of loamy Haplic Chernozems (Ch), the crop residues of winter wheat (WR) and oil rape (RR) and bio-stimulators BETA-LIQ (B) and TRICHOMIL (T) were used. Variants of laboratory experiment were following: Ch, Ch+WR, Ch+WR+B, Ch+WR+T, Ch+RR, Ch+RR+B, Ch+RR-T. During incubation optimal temperature and moisture for decomposition of organic matter were kept. During incubation the basal and potential respiration were determined, and the values of relative respiration were calculated. The crop residues of RR had marked effect on increase the basal and potential respiration and on stability of organic substances as compared to crop residues of WR. Crop residues of WR had more marked effect on decreasing of nitrogen utilization. A higher amount of easyutilized organic substances was found in variants with applied crop residues of WR as well. Tested bio-stimulators had effect on increase of basal respiration, but their effect was more marked in variants with WR. The effect of bio-stimulators was also very intensive in the end of incubation in variants with crop residues of winter wheat. From tested bio-stimulators B had more marked effect on basal and potential respiration. More easy-utilized organic substances were observed in variant with B as well as B had more marked effect on utilization of carbon and stability of organic substances as compared to T. The crop residues of WR had more marked effect on decrease the potential respiration dynamics than crop residues of RR and from bio-stimulators T, but only in variants with applied crop residues of WR.

Biochar can affect CO2 emission and C sequestration from soils, but little is known about the effects of its re-application and interaction with easily accessible substrates. Since most agricultural soils are continuously reworked, understanding the mechanics of CO2 evolution as affected by soil amendments and their combinations may have important lessons for the global effort to combat climate change. In this study carried out in a controlled environment, we tested the short-term effects of biochar, and its re-application at different rates, on the production of CO2 emission and C accumulation in samples of arable soils. We used a loamy Haplic Luvisol as the substrate and added varying amounts of biochar and sources of easily accessible N and C. We observed CO2 evolution for 20 days at optimal temperature and moisture conditions. We found that in the control treatment with no biochar, the total potential respiration after the addition of (NH4)2SO4 (N) and glucose (G) was increased compared to basal respiration. The addition of biochar reduced CO2 emission in the control, N- and G-stimulated treatments by 12–22, 13‒24 and 2‒21%, respectively. Conversely, the application of biochar increased CO2 emission in the combined NG treatment. Application of biochar at a higher rate, as well as its re-application, increased soil organic carbon content and reduced emission of CO2 into the atmosphere.
